TT600RE - Length of shock?
 

Hi there, anybody who knows the exact length of the Sachs shock on the TT600RE?

If you also know the free length of the TT600RE Pailoi fork spring, it's diameter and number og windings, it would be of great help!!!

Thanks!

Erik,
I have a 10 Mb manual for the 2004 model - it has data about the shocks.
I will email a copy to you if you want to get that - biggish, so you need broadband I guess, but it is up to you!

Cheers,

Dave

ps PM me with a good email address for you - if you do that, I will send it over to you.

Hi Walkabout, thanks for your offer. Though I have the file already, and it does not say anything about the length of the shock. It should be somewhere around 400 mm, but before I ask someone to tailor a new shock I need to know the exact length of the original one. As you know +/- 10 mm makes a world of difference at the end of the swing arm.

Hi,
There is info in the maintenance section and, maybe, elsewhere.
e.g. installed length of shock = 211 mm +\- 1.5 mm and spring length = 224 mm.
If you are sure it is the same manual then fair enough,

Cheers,

Dave

ps loads of other info about the front forks as well.

Yes, but the info about the fork is somewhat dubious. If you see page 2-3 the wheel travel is said to be 230 mm. Then go to page 2-12. There it says that the front fork travel is 277-283 mm (?). It makes me wonder of they have updated the old manual for the TTR and forgotten that the forks are new too. So I doubt what is written about the free length of spring, and in any case the file does not say anything about the springs diameter and number of windings.

Erik, as I have both in the garage I can measure them installed on the bike if you like. The problem is, as much as I would like to help, I am not going to strip them down! If it helps, the forks are 46mm on both and the R sits approx 50mm higher front and rear than the RE. I am considering swapping the suspension from the R to the RE. If it's any consolation the RE suspension seems to lose some of it's harshness after approx 10000 miles, or maybe I just got used to it!

Manual
 

I'll take your word on that Erik - I've been a tad engrossed with the other sections of the manual for a full strip down of the top end & change of gaskets, miscellaneous starting problems, the exhaust falling apart, and broken decompression and speedo cables (and this is a 6 year old bike with just a few Km on the clock!).

I have also noticed conflicting information in there,

Dave

Dave, you've got a good case there. In some aspects the TT600R with an E seems like a hasty way to squeeze two-three more production years out of an ageing model. The seemingly insufficient work with updating the manual is an example. Sorry about all your problems though. My bikes has been very reliable.

Thanks Leigh, I did consider stripping down the rear end to measure the shock, though it is a bloody lot of work. However, this morning I got - rather unexpectedly - a reply from the Sachs factory in Italy (when did anybody get any replies from Italy?). They wrote that the Sachs was 380 mm. Now, the Ohlins on the TT600R is 400 mm, so the 20mm less sounds correct considering that the RE is lower than the R yet all mounting parts are identical on both models. I guess this confirms your earlier theory that it is the shock itself that makes the RE lower.

I will have Wilbers making me a new shock. They have been very forthcoming about finding a sollution for the TT600RE, and I'll post my experiences as soon as I get them.
